HOSE-COUZPL1NG Application filed November 4, 1911. Serial No. 658,558.

To all whom it mag concern;

Be it known that I, HARRY B. Romnsorz, a citizen of the United States, residing at lift uskegon in the county of Mushegon and State of Michigan, have invented a no i and useful Hose-Coupler, of which the fo lowing is a specification.

This invention relates to hose couplings of the-male and female type, and'has for its object. to provide a coupling of this char-- acter which is simple in construction ren- :deringit cheap to mamitacturc; and convenient and etlicient in its use.

Another object is to provide a coupling of this character wherein the male and iteinale members are engaged in a novel manner.

A further object is to provide a com.- pressible member between the male and tomale members to force same into mentand to also prevent. the escape 01' the gas or liquid passing through the coupling. and also dispensing with the i'iecessity of machining either the male or female parts to provide a tight metallic fit.

With the foregoing objects in View this invention is embodied in the novel construction and combination of parts hereinafter described and claimed, reference being; had to the accoi'njimnying drawing, wherein Figure lis a side elevation of the coupler. Fig. 2 is a longitudinal central. section thereof. Fig. S'is a t agmentat elevation of the male member. Fig. -11: is a section on the line -l..--iof Fig. 2. Fig. is a section on the line 55 of Fig. Fig. (3 is a tragmental View in perspective oi the temale niez'uber.

l-lciterring in detail to the drawing the female member of the coupling is designated at 7 ha viug a hose nipple 9 projecting from the outer end thereof. This female member 7 prm'ided with a pair of inwardly projecting tiainetrically opposed lugs 1'? at its inner end the said lugs being square in contour. and with a secondary socket 21 in the outer end of its socket. A rubber or other resilient ring or washer 14- fits smigly within the primary socket 13 ot the fen'iale member and has a nipple 15 projecting therefrom and fitting snugly in the socket 521' and seating against the outer end of the socket. This ring or washer 14 is seated "tightly against the outer end of the primary socket of the female member and is retained therein by its frictional management with the female member.

The male member of the coupler com- Specification of letters Patent.

prises a cylindrical'head 12 having the hose nipple 8 projecting from the outer end thereof and having a nipple 16 projecting from the inner end thereof. This head 12 is provided with diametrically disposed longitudinal channels 20 extending throughout the length of the head and on its outer end the head is provided with spiral shoulders 19 extending between the respective channels 20. Each of the spiral shoulders 19 is prorided with a series of square notches 18. The bores 10 and 11 of the male and female members, respectively, are of equal diameter thus permitting the unobstructed passage of gases or liquid through the coupler and extend outwardly from the end of the nipple 16 and the secondary socket 21, respectivcly.

In assembling the members of the coupler, the head 1:? of the male member is inserted snugly into the primary socket 13 of the female member, the lugs 17 passing through the channels 20, and upon the head 12 passing the lugs 17 the two members are rotated with respect to Each other thus causing the lugs 17 to ride upon the spiral shoulders 19 causing the two members to be. forced tonether and at the same time the head of the male member coincides-with and engages the ring 11- causing the same to be compressed to yicldingly force the head outward and at the same time preventing-the escape of the gas or liuuid passing through the coupler. The notches 18 of the shoulders 19 are adapted to receive the lugs 17 thus retaining the two members in engaged position, and due to the outward tension of the'ring 14 the notches 18 are caused to tightly engage the lugs 17 to'prevent the rotation of the two members relative to each other.

By the provision of the spiral shoulders 19 and the series of notches 18 in each shoulden the two members may be adjusted at. various positions relative to each other, the ring 14 yielding pressing the head outward permitting the head to be forced inward to disengage the head from the lug 17 to permit the head to be rotated and cause the lugs 17 to ride upon the spiral shoulders and engage other notches 18. In detaching the.

with the channels 20 of the head 12 whereby the head may be withdrawn from the female r member. The ni pic 16 of the head 12 upon i also be increased or door being brought together cans the two members being attached, snugly enters the ring l l'and the nipple 15 thereby preventing the said nipple from being iorced out of position and the nipple in heing compressed also serving to make a se cure goint.

When the two members of the coupier are attached, the two bores 10 and. 11 are adapted to coincide thereby presenting a direct and unobstructed passage through the coupler.

it will thus be seen that the two members of the coupler may be readily and rapidly attached with each other and when attached with each other are prevented from being disengaged by external. forces such as the coupler is susceptible to in its ordinaryv use. The tension between the two members may eased as delsired or necessary, by pressingthe two members together to disengage the head 12 from the lugs 17 and then rotating the members'relative to each other to engage the lugs 17' in the other notches 18 as above described, or by disengaging the lugs 17 from the notches l8 and rotating the members in the proper direction, the lugs 17 may be brought into alinement with the channels 20 whereupon thp members may be detached from each on ierl This coupler is very simple in its construction, the two members beipg cast from suitable metal and need not-be machined. The two parts of the coupler may therefore be taken from the molds after they are cast and after being suitably cleaned in the customary mannermay he adaptedgt ring or washer 14 being inserte nto the female member. It is not 'nece ary for the head '12 to it tightiy into the female mem her for the reason that thetwo members in and thering or washcrl i't compressed thereby preventing the escap'eiof the gas or liquid passing throughwthe coupler and at the same time the said ring, forces the head outward causing the head to engage with the lugs 17 thereby locking the two members against rotationrelative to each bthen As a whole, this coupleris de'voidof complexity of parts and is on the other hand of very simple construction; which is the primary aim of this invention. The two members are capable of'co'n zni'ent and rapid atthe nipple 15.

tachment from each other,

in its various features being such as to be highly preferable over the various couplers now in use.

What is claimed is l. A coupling comprising a female memher having a primary and a secondary socket and abore extending from the secondary socket, a compressible ring in the female member seating against theend or the primarysocket and having a projecting nipple fitting snugly in theseeondaryflsoclret and seating against the'end there0f,:and a male member insertible into the primary socket to seat against and compress the sair ring and 'engageable in-the female member, the male member havinga nipple projecting therefrom of smaller diameter than the said secondary socket'and adapted to enter the said ring and its nipple and having a bore of equal diameter with the former bore and extending from the end of the nipple andand the coupler socket, and a male member having a head insertible snugly into the primary so ket of the female member, the said head-having alongitudinal channel for the passage of the said lug'and having a-s'piraL shoulder on its outer end provided with c lug. receiving notches, and the said head having a nipple of smallerdiam-eter than the said secondary socket adapted to enter the said ring and its nipple and the said head beingadapted to coincide with and compress the'said ring, the male member having a bore of equal diameter with the former bore and extending from the end of it-snipple and adapted to coincide with the'former bore.
